Answer:
38825.472 M
Explanation:
Using
C1V1=C2V2
To make solution B,
C1 = 25.527 M, V1 = 13 mL
C2 = 25.527 x 8 = 204.216 M
V2 = 13 X 12 = 156 mL
To make solution C'
C1 = 8 X 202.216 M = 1617.728
V1 = 8 X 156mL = 1248 mL
V2 = 4 X 13 = 52 mL
C2 = C1V1 / V2
=1617.728 X 1248 / 52
=38825.472 M
Answer:
14.99 mols of CO2
Explanation:
STP= 273 k , 1 atm , .0821 gas constant
N=PV/RT
N= 1x336/.0821x273
14.99 mols of CO2
659.6 grams of CO2
The amount of alcohol contained in each of the listed beverages can be compared as follows; 1/2 oz of 80 proof liquor > 5 oz of wine (12% alcohol) > 12 oz of wine cooler (5%alcohol) = 12 oz of beer (5%alcohol) .
A drink that contains alcohol must be an intoxicating beverage. The extent of intoxication of an alcoholic beverage depends on the amount of alcohol that the beverage contains. There are various types of alcoholic beverages as listed in the question.

Answer:
1.08mol
Explanation:
moles = reacting mass/ molecular weight
reacting mass = 80.0g molecular weight of Ca[OH]2= 40 + 2(16 +1) = 74g/mol
mole = 80.0/74 = 1.08mol
Answer:
The volume of the gas at a pressure of 65.0 kPa would be 363 mL
Explanation:
Boyle's Law is a gas law that relates the pressure and volume of a certain amount of gas, without temperature variation, that is, at constant temperature.
Boyle's law states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant. In other words, the product P · V remains constant at the same temperature:
P*V=k
Being P1 and V1 the pressure and volume in state 1 and P2 and V2 the pressure and volume in state 2 are fulfilled:
P1*V1=P2*V2
In this case:
- P1= 45 kPa= 45,000 Pa (being 1 kPa=1,000 Pa)
- V1= 525 mL= 0.525 L (being 1 L=1,000 mL)
- P2= 65 kPa= 65,000 Pa
- V2= ?
Replacing:
45,000 Pa* 0.525 L= 65,000 Pa*V2
Solving:
V2=0.363 L=363 mL
<u><em>The volume of the gas at a pressure of 65.0 kPa would be 363 mL</em></u>
